AB  - This paper presents a reconfigurable digital implementation of an event-based 
      binaural cochlear system on a Field Programmable Gate Array (FPGA). It consists 
      of a pair of the Cascade of Asymmetric Resonators with Fast Acting Compression 
      (CAR-FAC) cochlea models and leaky integrate-and-fire (LIF) neurons. 
      Additionally, we propose an event-driven SpectroTemporal Receptive Field (STRF) 
      Feature Extraction using Adaptive Selection Thresholds (FEAST). It is tested on 
      the TIDIGTIS benchmark and compared with current event-based auditory signal 
      processing approaches and neural networks.
